In this communication, we develop a facile one-pot green strategy toward CuO–Cu2O–Cu nanorod-decorated reduced graphene oxide (CuNRs–rGO) composites by hydrothermal heating of the mixed solution of GO and Cu(OAc)2 under basic conditions without the use of extra reducing agents. As-synthesized composites have been succ…
We demonstrate a facile, generic method for the fabrication of highly dense long range hexagonally ordered various inorganic oxide nanodots on different substrates by using a microphase separated polystyrene-b-poly(ethylene oxide) (PS-b-PEO) block copolymer (BCP) thin film as a structural template. The method does not…
A versatile macro-initiator with dual functional anchoring groups for surface-initiated atom transfer radical polymerization (SI-ATRP) on various substrates is reported. Conventional free radical copolymerization was performed with N-(3,4-dihydroxyphenyl) ethyl methacrylamide (a dopamine anchor-containing monomer), 4-…
In the present paper, NaLa(WO4)2 microcrystals with diverse morphologies, sizes and dimensions have been synthesized via a mild and controllable hydrothermal process using polyvinylpyrrolidone (PVP) as surfactant. The phases, morphologies, sizes, and photoluminescent properties of the as-prepared products were well ch…
Herein we report the intra- and inter-molecular assembly of a {V(5)O(9)} subunit. This mixed-valent structural motif can be stabilised as [V(5)O(9)(L(1-3))(4)](5-/9-) (1-3) by a range of organoarsonate ligands (L(1)-L(3)) whose secondary functionalities influence its packing arrangement within the crystal structures.…
Graphene oxide (GO), nano/micro-structured polyaniline (PANi) are some typical important functional materials, which have many applications in lithium ion battery with high energy, supercapacitor, catalysts, solar cells, nanodevices, chemical sensors, biosensors and biomedical fields. In this paper, GO was obtained by…
A three-dimensional (3D) porous aromatic framework (PAF-14) with high fluorescence quantum yield was synthesized from luminescent monomer of tetra(4-dihydroxyborylphenyl)germanium (TBPGe) building blocks. The powder X-ray diffraction (PXRD) analysis of the experimental and simulated patterns indicate that PAF-14 is hi…
A combined UV-visible, cyclic voltammetric theoretical and hyper-Rayleigh scattering study has been carried out on a new series of ferrocenyl chromophores (2a–2d and 7–11) to develop a structure–property relationship, by varying the acceptor strength and the conjugation path length between the donor and the acceptor a…
This paper describes the effect of using different titanium precursors on the synthesis and physical properties of SrTiO3 powders obtained by microwave‐assisted hydrothermal method. X‐ray diffraction measurements, X‐ray absorption near‐edge structure (XANES) spectroscopy, field emission scanning electron microscopy (F…
ASTM C1202 tests were conducted at various ages with the corresponding surface resistivity test, and the results were compared. Samples tested included field- and laboratory-prepared samples. The laboratory test matrix tested several mixtures common to Louisiana at a wide range of ratios of water to cementitious mater…
This paper reports the conversion efficiency (CE) and packaging efficiency (PE) of white phosphor-converted light-emitting diodes (pc-LED) with four morphologically different phosphors, such as nanophosphors (NPs), thin-film phosphors (TFPs), ceramic plate phosphors (CPPs), or micro-size powder phosphors (MPPs) to sea…
Gold nanoparticles (∼5 nm) coated with plasma-polymerized allylamine were produced through plasma vapor deposition and bioconjugated with a monoclonal antibody targeting the epidermal growth factor receptor. The resulting nanoconjugates displayed an antibody loading of about 1.7 nmol mg−1 and efficiently target epider…
Samples of medium carbon steel were examined after heating between 900C -980C and soaked for 45 minutes in a muffle furnace before quenching in palm oil and water separately. The mechanical behavior of the samples was investigated using universal tensile testing machine for tensile test and Vickers pyramid method for…
Zinc alkyl cations supported by N,N-BIAN-type bidentate ligands were found to be highly active in the immortal ROP of ε-caprolactone to yield narrowly disperse and chain length-controlled poly(ε-caprolactone), whether in solution or bulk polymerization conditions.
Natural polymers such as proteins and polysaccharides though very useful exhibit a limitation in their reactivity and process ability. These shortcomings were overcome by chemical and physical alteration of natural polymers. Among various investigations, the interpenetrating polymer networks (IPNs) for hydro gels have…
One of the serious problems of oil extracting indus try is the corrosion process. The successful applic ation of carbon steels in oil and gas pipelines and production tubular in Carbon Dioxide (CO 2) containing environments depends mainly on either the formation of protective corrosion product film or the use of corro…
Carbon nanofibers/tubes (CNF/Ts) are very strong and stiff and as a result, are expected to be capable of enhancing the mechanical properties of cementitious materials significantly. Yet there are practical issues concerning the utilization of CNF/Ts in cementitious materials. This study summarizes some of the past ef…
We have developed a surface-enhanced Raman scattering (SERS) nanosensor firstly for Ag ions and Ag nanoparticles detection based on 2-mercaptoisonicotinic acid (2MNA)-functionalized Au nanoparticles. Ag(+) can coordinate with 2MNA resutling in a variation of its SERS spectrum, which is used as a criterion to determine…
In tuning the sub-particle localisation of Gd(III) binding macrocycles within a mesoporous scaffold, nanoparticle contrast agents of unprecedented relaxivity and low Gd(III) loadings can be realised.
We study the effect of interfacial curvature on the binding energy and forces exerted on small spherical particles that adsorb on an interface between two immiscible liquids. When the interface has anisotropic curvature, the constant-contact-angle condition at the particle-fluid boundary requires a deformation of the…
